Dotweb frame Tour [II]-Common object-app (dotweb)

Dotweb belongs to a web framework that wants to help developers quickly build Web applications, improve development efficiency, and reduce unnecessary code bloat through framework behavior.

The dotweb contains several common objects:

• App (Dotweb) app container that provides the necessary container class functionality for Web request processing.
• Httpserver A service module that is used to truly handle Web requests.
• HttpContext is used to provide quick processing and unique access to request information and response information in a single request processing.
• The Response is used to send output from the server to the user.
• Request is used to obtain information from the user.
• Session is used to store information about a connection session, or to modify related settings. Currently supports storage of native memory with Redis distributed.

At the beginning of this chapter, this series of objects will be described in common scenarios.

The App object, defined as Dotweb in Dotweb, is primarily responsible for providing the necessary container class functionality for Web request processing, such as starting web snooping, configuring initialization, setting the operating mode, setting up the log, setting up the cache, and also taking on a range of shortcut function portals.

Main properties:

Property	Describe	Default value
Httpserver	App-hosted Webserver objects	Newhttpserver ()
Config	Global configuration information, mapping dotweb.conf	Config. Newconfig ()
Middlewares	App-Level middleware collections	Make ([]middleware, 0)
Exceptionhandler	Custom Handling Exception methods	Defaulthttperrorhandler ()
Notfoundhandler	Custom 404 Request Processing Method	Defaultnotfoundhandler ()
Methodnotallowedhandler	Custom 405 Request Processing method	Defaultmethodnotallowedhandler ()
AppContext	App-level global memory kv storage	Newitemcontext ()
Offlineserver	Maintenance webserver	Newofflineserver ()

Main methods :

Method	Describe
Start ()	Start the web port monitoring according to the configuration, and if an error occurs, return the specific Error object
Listenandserve (Addr string)	Specify host:port to initiate web port monitoring based on configuration
Use (M ... Middleware)	Register middleware, all request sharing
Setdevelopmentmode () \setproductionmode ()	Set development mode \ production mode
Cache ()	Provides a global memory cache entry
Userequestlog ()	Enable the base request log middleware
Setpprofconfig ()	Setting Pprof Listening port information
Setlogger (log logger. Applog)	Set up custom log plug-ins

General Usage Code:

Func Main () {//Initialize AppApp: =Dotweb. New ()//set the Dotserver log directory//if not set, default is not enabled and defaults to the current directoryApp. Setenabledlog (true)    //turn on development modeapp. Setdevelopmentmode ()//set up RoutesInitroute (app. Httpserver)//Custom 404 Outputapp. Setnotfoundhandle (func (ctx dotweb). Context) {ctx. Response (). Write (http. Statusnotfound, []byte("is ' t app ' s not found!"))    })    //Start the Monitoring serviceApp. Setpprofconfig (true,8081)    //Global ContainerApp. Appcontext.set ("app","Dotweb")    //Start ServicePORT: =8080FMT. Println ("Dotweb. StartServer ="+StrConv. Itoa (port)) Err:=app. StartServer (port) fmt. Println ("Dotweb. StartServer error =", err)}
